求翻译：燃料电池汽车：燃料电池中的氢与氧不经历热机过程，直接把燃料的化学能转化为电能，效率达到60%～80%，是普通内燃机热效率的数倍，基于氢源的燃料电池技术的发展，使电动汽车脱离了传统的以电方式补充能量的方式，而采用加入“燃料”的方式补充能源，使电动汽车使用范围不受充电设施的限制。国外企业对革命性的清洁型汽车寄予厚望，纷纷开始开发燃料电池汽车的关键技术。各大汽车公司大都推出了品种繁多的各式各样的车。由于燃料电池不能提供车辆起步、加速所需的瞬时大功率，且无法吸收车辆制动的能量，因此需要与其它蓄能元件一起组成燃料电动汽车的动力源。是什么意思？

Fuel cell vehicles: hydrogen for fuel cells and oxygen do not experience thermal process fuel directly to the chemical energy into electrical energy, and efficiency to 60 % ~ 80% efficiency, which is ordinary internal combustion engine, based on the number of times the hydrogen fuel cell technology

Fuel battery car: fuel battery in the of hydrogen and oxygen does not experience heat engine process, directly to fuel of chemical energy transformation for power, efficiency reached 60%~80%, is general internal combustion engine thermal efficiency of number times, based on hydrogen source%2
